Circulator Pump, 42 LPM, 4 m Head, Cast Iron, Check Valve

High efficiency circulator pump boosts hot water circulation to reduce wait time and improve heating response in home systems. Built with a heavy-duty cast iron body and an ECM permanent magnet motor, it delivers quiet operation (≤45 dBA) while keeping power draw low. Multiple modes with AUTO adjustment and night operation help match output to demand, supporting stable flow for underfloor heating, radiators, and solar water heaters.

• Delivers up to 42 LPM flow and 13 ft/4 m max head for responsive hot water recirculation


• Runs at ≤45 dBA with ECM permanent magnet motor and insulated design for quieter heating


• Adjusts output with multiple modes plus AUTO adjustment and night mode to limit wasted energy


• Prevents backflow with a built-in check valve for steadier circulation and fewer temperature swings


• Installs fast with threaded connection and included fittings for straightforward replacement projects

Designed for homeowners and installers who want reliable circulation without bulky hardware, this space-saving pump supports a wide water temperature range and stable performance under heat. Use it to improve circulation in radiator loops, underfloor heating manifolds, and compatible solar hot water systems—especially where slow return lines cause long waits. Confirm your connection size and required head/flow before ordering, then grab yours today to streamline your heating and recirculation setup.
